Dogs and Rockers

I went to Seaton this afternoon to have a walk along the seafront before visiting C.  I couldn't believe how warm it was!
I spotted this trio about to board their motorbike - Mum, Dad, and Pooch, complete with helmet, and according to a bit of overheard conversation, her own audio system too so that she can hear them speaking and  presumably also hear any music that might be played through the system. 
They said that she loves travelling on the motorbike and gets really excited when she realises they're going out on it. 
I'm just waiting for the dog and or motorbike jokes now! Can of worms.....
